To all' whom it may concern.'

-Be 'it lmown thatfI, ERxEs'r R. ZIMMER- MAN, a citizen of theUnitedStates, residing at Chicago, in the'- c'ounty of Cook and StateoffIllinois, have invented' a certain new and useful Improvement inCombined Mops and lVringers, of which the fol-lowing is a specification.

My invention 'relates to combined-mops and wringers and the generalobject of the y invention is to providea ldevice of this class whichshall be simple inform andl durable and capable of manipulation with theleast possible eifort on the-part of the user.

Among the specific objects ofthe inveiition are:ii'st, to provide "adevice of -this class in which the wringer is unlocked when the mop isin wringing position but becomes automatically locked when the Amop isbrought to scrubbing position. Second, to provide a construction suchthat the center 'of'gravity' of the-'device as a wholeis shiftedmaterially inward when'the parts are brought to wringing position thusmaking the device much easier to manipulate' and reducing the-'apparentWeight thereof in the han'ls 'of the iiser. Third, to provide aconstruction siich that the mop may hang sub-` stantially 'Vertical`when in. wringingiposition `while 'the handle remains approximatelylhorizontal thus making the device easier'to handle. Fourth, to providemeans or'lii'niti-ng'the inswing' of the mop when in wringing .positionthus 'avoiding any danger of the moptouching the clothing of the userduring the act 'of wringing. Fifth, to provide means for limiting the upswing oi the' mop relatively to the handle.

l accomplish my objects by the mechanism illustrated in the'accompanyingdrawings in which- Figure 1 isa side elevation of the'mop and wringer inacting' position. lli`ig.-2 is a side elevation showin-g the parts inwringi'ngposition. vFig. 3 is aplan viewvoic the parts as shown in Fig.1, the handle being omitted in order to better reveal'the constructionot the parts beneath. Fig. 4 is a sectional detail on Athe line 1 4,Fig. 3. Similar numerals refer to similar parts throughout the severalviews.

At the lower end 'of the'handle'l is an extension consisting inthepresent form-ot arms'2, preferablytwo in number, fastened to the handle'by a socket or`ferrule 3 or 'other suitablemeans. By preference saidextension consists of a single bifurcated casting, as shown. A-rame isconnected bv pivots 4' to-tlie lhandle extension at apoirit between theends of the arms 2. At the lower end ofthe arm of the frame is a loop 6for supporting-the outer end of the mop 7. The inner end-of the mop issupportedby 'a hook or loop 8 formed at the outer end `of a shaft 9journaled in the bearing 10 formed at the lower end of the arm 1l.' ofthe pivoted frame. It is desirable that the:` parts beso congured'thatshaft 9 `and the arm-5 of the pivot'ed frame will lie approximatelyparallel to each other on opposite sides of the pivots 4. Shaft 9 isrotated byia crank lfprovided'w'ith a handle 13. andthe arrangement issuch that whenthe. parts are'in acting or'scrubbingposition said crankwill extend upward from shaft 9, passing between the two branches of thehandle extension and being thus locked betweensaid branches; -but -wlienthe mop is permitted todropto wringing positiony the pi'voted framewill' swing the crank up-clear of said'branches and permit thecrank'tobe rotated.

The mop isrheld to its work 4by va foot which, in t'lieipresent design,consists of a base 15 having an arm 16 at the inner end and anfeye17-fat its outer-end. `The arm 16 is vconnected by the pivots 18, 1-8 tothe outer end 'of the arms 2. The eye 17 encirclesthe 'arnii off-thepivoted frame at the outer end. The sliding movement/of said eyeupon-arm 5 islimited by astop 19 formed upon' arm 5. As the crank 12passes up-between the vbranches ofthe handle eX- tension, the upswing-of the mop from scrubbing vposition might well be limited by thecrank itself abutting the crotch of said extension. Or, -th`e movementmight be limitedI by the handle 13 striking the top of said extension.-lt is preferable. however, to provide special stops for limiting the upswing. v'lhisl accomplish b v forming stops QO'on-froin :"i'in positionto abut the stops 21 on the 'arms-2 of the handle extension when the mopis in scrubbing position as shown in Fig. 1. As a result ofthesecooperating stops the up swingis limited and the user may, it desired,cause onlythe outer or forward cud of the mop to exert pressure on thillloor. [n other words, with my construction it is possible to vary thepressure at different points, producing, at will, greater pressure atthe inner end or at the outer end or producing approximately uni-4 form|A ressure throughout the length of the 1 to cause the foot to tightenthe mop. Hence y by thus limiting the up swing of the frame,

' the tighteiing ot the mop is limited and the inop may be soproportioned as to leave it pute loose when the device is in scrubbingposition. A loose mop does its work better than a tight one andhence'iny device has a decided advantage in this respect.

In operation, when the mop is in use it 5 will be held to the floor bythe foot and will be held extended through the coperation of the loop 6on arm 5 and the hook 8 on shaft 9. It will be noted that the foot ispivoted to the handle extension at a point beyond the pivots 4. Theresult is that the portionsQl of the arms 2 act as levers' to swing theinner end of the vfoot away from arin 5 when the mop is in actingposition,

the eye 17 acting as a pivotal point about which the foot swings towardor from the arm 5'. When the user wishes tol immerse the mop' or wring'it, he simply lifts Ythe handle, whereupon gravity a'ctingvupon the mopand its supports causes-the 'parts to drop to the position shown in Fig.There are several advantages in this; tirst, as the parts swing tovertical position the centexof gravity' moves toward the hand ofthe userand hence the weightzofthe device does not seem as great as itv would ifthe parts-reina-ined approximately horizontal, as shown in Fig. 1.Second, this'position is very convenient 'for it renders it easy tolower 'the mop into the bucket or other ,vessel containing thewater forscrubbing. Third, it unlocks the handle. Fourth, it brings the crankinto a convenient position to beI rotated. As the eye 17 slidesalongithe --erm 5 it approaches the stop .19, Whichis'so placed as toarrest the downswing of arm 5 when the parts reach .approxiniatel avertical position, as shownlin Fig. 2. he portions 28 of the arms 2cause the foot to move away from the mop when the parts swing towringing position, thuspermitting the mop go be wrung without beinghindered vby the OO'. .-'I n.' f .v if
